Anti-NCKX4 antibodies enable researchers to detect and measure the NCKX4 antigen in biological samples. This target is a reported synonym of the SLC24A4 gene, which encodes solute carrier family 24 member 4. This protein is known to function in the regulation of intracellular calcium, among other biological roles. The human version of NCKX4 has a canonical amino acid length of 622 residues and a protein mass of 69 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cell membrane and cytoplasm of cells. NCKX4 is a member of the Ca(2+):cation antiporter (CaCA) (TC 2.A.19) protein family.
